Posted yesterday but only got one response.. so here it goes.

I have 2 apps that I use to track my period (not sure why). Glow said 9 days til period. My other app says 1 day late. My boyfriend and I had sex this morning. I had slight pain during (like he would’ve been hitting my cervix) and period like bleeding during/after (we noticed after we finished). This is the 2nd time I’ve changed my tampon since. This time, there is only a little brown spotting. Any ideas what could be going on? TIA.
